Setup and Installation

In nthis nsection, nwe nare ngoing nto nlook nat nhow nto nsetup nC# non nyour ncomputer nand nstart ncreating nC# nprograms. nBefore nwe nbegin nthis nenvironment ninstallation, nyou nneed nto nmeet na nfew nrequirements nnecessary nfor nrunning nthe nC# nIntegrated nDevelopment nEnvironment n(IDE). nFor ncompatibility nissues nand nefficient nexecution nof nthe nprograms, nensure nthat nyour ncomputer nmeets nthe nfollowing nrequirements:

❖ n n nA n1.8Ghz nand nhigher nProcessor n– nPreferably na n64-bit nprocessor

❖ n n nWindows n7 nService nPack n1 nand nhigher

❖ n n n4GB nof nRAM nand nabove n(6GB nfor nbetter nperformance)

❖ n n nMinimum nDisk nSpace nof nat nleast n8GB nto n210 nGB ndepending non nthe nfeatures nyou nwant nto nbe ninstalled

❖ n n nMicrosoft n.NET nFramework n4.5 nand nhigher

❖ n n nFor nthe ninitial nsetup, nyou nneed na nrelatively ngood ninternet nspeed.

These nbasic nrequirements ncan ndetermine nwhether nC# nwill nrun nsmoothly non nyour nSystem nor nnot. nIf nyou nhave nthe nabove nrequirements, nwe ncan nbegin.

How nto ninstall nthe n.NET nFramework
